Reviews new research into what young children know about emotions and how their knowledge may develop. Notes that the developmental timetable for the emergence of various emotion states and expressions is well documented and that teachers need to take into account individual and sociocultural differences in children's emotional behavior. (MDM)

Comments on Gauvain's discussion, in this issue, of the development of thinking from a sociocultural perspective, expanding her analysis by comparing research on apes who have developed in natural habitats with apes raised by humans in something resembling a human culture. Argues that the study of nonhuman primates can contribute to the emerging…

Examines issues related to the design and interpretation of high-risk depression research, including the identification of symptoms and syndromes, categorical versus dimensional scales, aspects of depression to be considered, specificity of effects, use of process measures, and conceptualization of risk and resilience. (MDM)

"The Bell Curve" declares that studies of separated identical twins--the "purest" of "direct" methods for estimating IQ heritability--indicate a value of +.75-+.80. But, the main study cited suggests a heritability of "two-thirds" for the middle class, and Herrnstein and Murray neglect to mention numerous…

The goals of exploratory and confirmatory factor analysis are described, and procedural guidelines for each approach are summarized, emphasizing the use of factor analysis in developing and refining clinical measures. Recent examples of the use of factor analysis are reviewed and used to highlight controversies that can emerge. (SLD)

Difficulties in defining and examining ethnicity as a variable in psychological research are explored, and it is asserted that many problems in assessment research arise from not making explicit the assumptions underlying the use of ethnicity as an exploratory variable and from inadequately describing cultural and contextual characteristics of…

Outlines an explanatory framework for psychological sex differences, one that is anchored in the new theoretical paradigm of evolutionary psychology. This paradigm rejects the dichotomy between biology and environment and provides a new metatheory of why sex differences exist, where they exist, and in what contexts they are expressed. (GR)

Examines preschool children's ability for advance planning and mishap prevention or remediation related to familiar events. Indicates that children three to five years old appear to use general event knowledge in constructing verbal plans. However, developmental differences in the quality of plans suggests that the ability of using general…

An ex post facto longitudinal study of 500 diagnostic protocols supported the often voiced criticism that psychologists diagnosing learning difficulties frequently follow principles that are remote from teaching and learning processes. Analyses of the actual learning process were very few. Learning difficulties were usually conceived in terms of…

Presents results of Scherdan's revised Myers Briggs Type Indicator (MBTI) study, and compares outcomes to past MBTI studies to disprove librarian stereotypes. Scheridan's 1992 study used responses from 1,600 librarians to determine psychological types and personality profiles. Discussions and tables compare results to the general population, other…

Examined the role of prior temporal knowledge of 4 1/2- and 6-year-olds through the use of high-rate, interval, and minimal instructions in a fixed-interval training schedule. Determined that the subjects' learning depended on their verbal self-control skills. (BC)

New methods for comparing the medians corresponding to independent treatment groups are suggested. Procedures are based on the estimator of F. Harrell and C. Davis in conjunction with a modification and extension of the bootstrap calibration technique suggested by W. Loh. Data from two groups provide an illustration. (SLD)

A probabilistic choice model, based on L. L. Thurstone's Law of Comparative Judgment Case V, is developed for paired comparisons data about psychological stimuli. The model assumes that each stimulus is measured on a small number of physical variables. An algorithm for estimating parameters is illustrated with real data. (SLD)

Summarizes the use of field experiments designed to investigate personal space invasion. States that the experiments were designed and conducted by introductory psychology students and complemented by classroom lectures. Reports that the experiments provided an understanding of personal space, personal space invasion, and the implications…

Comments that fuzzy-trace theory is broadly comprehensive and contains compelling experimental manipulations; debates assumptions of the theory. Describes aspects of the historical and theoretical context of the theory and its usefulness in organizing false memory phenomena. Suggests some limitations concerning the representation of child…
